[0072] Some embodiments of the present application will be described in detail below with reference to the accompanying drawings.

[0073] See also Figure 1 and Figure 2 The embodiment of the present application provides a clamping mechanism 100, which is used to clamp multiple workpieces 200 at a time to improve the processing efficiency of the workpieces 200 and save manpower. The clamping mechanism 100 includes a base 10, a bearing seat 20, a clamping assembly 30, a driving assembly 40, an abutting assembly 50 and a connecting assembly 60. The bearing seat 20 is arranged on the base 10, and a bearing groove 21 for bearing the workpiece 200 is opened on the bearing seat 20. The clamping assembly 30 is accommodated in the bearing groove 21, and the clamping assembly 30 cooperates with the groove wall of the bearing groove 21 to clamp the workpiece 200. The driving assembly 40 is arranged on the base 10 and is located below the bearing seat 20. The driving assembly 40 is penetrated through the bearing seat 20 and connected to the clamping assembly 30. The driving assembly 40 drives the clamping assembly 30 to actuate so that the clamping assembly 30 cooperates with the groove wall of the bearing groove 21 to clamp the workpiece 200. The abutting assembly 50 is disposed on the base 10 and located on one side of the bearing seat 20. The abutting assembly 50 is used to abut against the workpiece 200 in the bearing groove 21. The abutting assembly 50 cooperates with the clamping assembly 30 to fix the workpiece 200. The connecting assembly 60 is connected to the base 10. The connecting assembly 60 is also connected to an external motion mechanism (not shown). The external motion mechanism drives the connecting assembly 60 to move, so that the entire clamping mechanism 100 moves, so that the clamping mechanism 100 drives the workpiece 200 clamped on the clamping mechanism 100 to move, so as to facilitate multi-angle processing of the workpiece 200 clamped by the clamping mechanism 100.

[0074] The base 10 includes a bottom plate 11, a top plate 12 arranged opposite to the bottom plate 11, and two support plates 13 arranged at intervals and connected between the bottom plate 11 and the top plate 12. The bottom plate 11 is located below the top plate 12, and the support plates 13 are generally hollow structures. Among them, the bearing seat 20 is arranged on the side of the top plate 12 away from the bottom plate 11, the driving assembly 40 is arranged on the bottom plate 11 and located between the two support plates 13, the abutment assembly 50 is arranged on the side of the top plate 12 away from the bottom plate 11 and located on one side of the bearing seat 20, and the connecting assembly 60 is connected to at least one of the top plate 12 and the support plate 13. Specifically, in this embodiment, the connecting assembly 60 includes a disk 61 arranged on one side of the base 10 and two reinforcement members 62 arranged at intervals and connected between the top plate 12 and the disk 61, and the two reinforcement members 62 are located between the two support plates 13, and the two reinforcement members 62 are both hollow structures, and the connecting assembly 60 is connected to the external motion mechanism through the disk 61. Thus, by setting the specific structure of the base 10, the base 10 can achieve the effect of installing the bearing seat 20, the driving assembly 40, the abutting assembly 50 and the connecting assembly 60; by setting the specific structure of the connecting assembly 60, the connecting assembly 60 can achieve the effect of connecting with the top plate 12 of the base 10 and the external motion mechanism. It can be understood that the two reinforcement members 62 can also be connected to the two support plates 13 respectively.

[0075] In the embodiment of the present application, the number of the bearing seats 20 and the abutment assemblies 50 are both two, and the two bearing seats 20 and the two abutment assemblies 50 are respectively arranged on the top plate 12 at intervals, and the two abutment assemblies 50 are located between the two bearing seats 20. Two clamping assemblies 30 are arranged on each bearing seat 20, and every two clamping assemblies 30 cooperate with the corresponding bearing seats 20 to clamp four workpieces 200. It can be understood that in other embodiments, more than two clamping assemblies 30 can be arranged on each bearing seat 20, so that the clamping mechanism 100 can clamp more workpieces 200 at a time.

[0076] See also Figure 3The bearing seat 20 includes a substrate 22 disposed on the base 10, three stoppers 23 arranged at equal intervals on the substrate 22, and a stopper bar 24 connected to the three stoppers 23 and located on one side of the three stoppers 23. The substrate 22, the three stoppers 23 and the stopper bar 24 enclose the two bearing grooves 21, the upper side of the substrate 22 can be understood as the groove bottom of the bearing groove 21, and the side of each two adjacent stoppers 23 facing each other can be understood as the groove wall of the bearing groove 21. It can be understood that when a clamping assembly 30 is provided on each bearing seat 20, the number of the stoppers 23 can also be two, the two stoppers 23 are arranged on the substrate 22 at intervals, the two ends of the stopper bar 24 are respectively connected to the two stoppers 23, and the substrate 22, the two stoppers 23 and the stopper bar 24 enclose a bearing groove 21. Alternatively, when more clamping assemblies 30 (for example, N, where N is a natural number greater than 3) are arranged on each supporting seat 20, the number of the block 23 can also be more (for example, N+1, where N is a natural number greater than 3), more block 23 are arranged at intervals on the substrate 22, and the baffle bars 24 are connected to the more block 23, and the substrate 22, more block 23 and baffle bars 24 are combined to form more supporting grooves 21 (for example, N, where N is a natural number greater than 3).

[0077] See also Figure 4 The clamping assembly 30 includes an inclined pin 31 which is accommodated in the bearing groove 21 and has an inclined surface, and two clamping members 32 which are respectively arranged on both sides of the inclined pin 31 and respectively connected with the inclined surfaces of the inclined pin 31. The two clamping members 32 are both slidably arranged in the bearing groove 21. The inclined surfaces of the inclined pin 31 push the two clamping members 32 to move closer to or away from each other. The inclined pin 31 is roughly an isosceles trapezoidal structure. Among them, the driving assembly 40 is penetrated through the top plate 12 and the bearing seat 20 and connected with the inclined pin 31 of the clamping assembly 30. The driving assembly 40 drives the inclined pin 31 to move toward the bottom of the bearing groove 21 (which can also be understood as the base plate 22), so that the inclined pin 31 cooperates with the inclined surface of the corresponding clamping member 32 to push the corresponding clamping member 32 toward the groove wall of the corresponding bearing groove 21, so that the clamping member 32 and the bearing seat 20 clamp the workpiece 200. In this way, by setting the above-mentioned clamping assembly 30 having an inclined pin member 31 and two clamping members 32, the vertical force of the driving assembly 40 is converted into a horizontal force through the inclined pin member 31, so that the two clamping members 32 move away from each other to cooperate with the groove wall of the corresponding bearing groove 21 to clamp the workpiece 200.

[0078] Specifically, each clamping member 32 is provided with an avoidance groove 321 on one side facing the base plate 22, and correspondingly, a limiting portion 25 is provided on the base plate 22 (see Figure 3), the limiting portion 25 extends into the avoidance groove 321. In this way, by providing the avoidance groove 321 and the limiting portion 25, the clamping member 32 is slidably arranged in the bearing groove 21 through the cooperation of the avoidance groove 321 and the limiting portion 25, and the moving direction of the clamping member 32 is limited by the cooperation of the limiting portion 25 and the avoidance groove 321, thereby ensuring the moving accuracy of the clamping member 32.

[0079] I-shaped slide rails 311 are respectively provided on both sides of the oblique pin 31, and an I-shaped slide groove 322 is provided on the side of each clamping member 32 facing the corresponding oblique pin 31. Each clamping member 32 is slidably connected through the cooperation of the I-shaped slide groove 322 and the I-shaped slide rail 311, which can also be understood as the clamping member 32 and the oblique pin 31 are roughly I-shaped slide rail slider structures. In this way, by providing the above-mentioned I-shaped slide rail 311 and I-shaped slide groove 322, on the one hand, the clamping member 32 and the oblique pin 31 are slidably connected, and on the other hand, the stable cooperation connection between the clamping member 32 and the oblique pin 31 is ensured to avoid the situation of misalignment and separation between the clamping member 32 and the oblique pin 31.

[0080] Furthermore, each clamping assembly 30 further includes an elastic member 33 disposed between the oblique pin member 31 and the clamping member 32. In the present embodiment, the number of the elastic members 33 is four, and each clamping member 32 corresponds to two elastic members 33. The elastic members 33 are springs. Two elastic members 33 are disposed between the oblique pin member 31 and the corresponding clamping member 32, and each elastic member 33 extends substantially along the moving direction of the oblique pin member 31. Specifically, first receiving grooves 312 extending from bottom to top are respectively provided on both sides of the oblique pin member 31 near the corresponding I-shaped slide rail 311, and a second receiving groove 323 is provided on the side of each clamping member 32 facing the oblique pin member 31. The first receiving groove 312 and the second receiving groove 323 are both substantially semi-cylindrical grooves, and the elastic member 33 is located in the corresponding first receiving groove 312 and the second receiving groove 323. In this way, by setting the above-mentioned elastic member 33, when the driving component 40 drives the oblique pin member 31 to move toward the bottom of the bearing groove 21, the oblique pin member 31 moves toward the bottom of the bearing groove 21 and compresses the elastic member 33 and pushes the corresponding two clamping members 32 away from each other by cooperating with the inclined surface of the clamping member 32; when the driving component 40 removes the driving force on the oblique pin member 31, the elastic member 33 elastically recovers to push the oblique pin member 31 to move away from the bottom of the bearing groove 21, and makes the oblique pin member 31 drive the corresponding two clamping members 32 closer to each other.

[0081] Furthermore, each clamping assembly 30 also includes a limiting member 34 connected to the oblique pin member 31 and movably stopped and penetrated through the substrate 22 of the bearing seat 20. In the present embodiment, the limiting member 34 includes a first limiting portion 341, a second limiting portion 342 and a third limiting portion 343 connected in sequence, a diameter of the second limiting portion 342 is larger than a diameter of the first limiting portion 341 and a diameter of the third limiting portion 343, the first limiting portion 341 is connected to the side of the oblique pin member 31 facing the bearing seat 20, the second limiting portion 342 is located on the side of the substrate 22 of the bearing seat 20 facing the oblique pin member 31, and the third limiting portion 343 is movably penetrated through the substrate 22 of the bearing seat 20. In this way, by setting the above-mentioned limiting member 34 including the first limiting portion 341, the second limiting portion 342 and the third limiting portion 343 connected in sequence, when the driving component 40 drives the inclined pin 31 to move toward the bottom of the groove of the bearing groove 21 (that is, the substrate 22), the inclined pin 31 drives the limiting member 34 to move, and the third limiting portion 343 moves in the substrate 22 of the bearing seat 20. Since the diameter of the second limiting portion 342 is larger than the diameter of the third limiting portion 343, the second limiting portion 342 cannot be penetrated into the substrate 22 of the bearing seat 20, so that the substrate 22 of the bearing seat 20 forms a stopper effect on the limiting member 34, and then forms a stopper on the inclined pin 31, thereby ensuring the movement accuracy of the inclined pin 31.

[0082] See also Figure 5The driving assembly 40 includes a driving member 41 arranged on the base 10 and located below the supporting seat 20, a first pulling block 42 rotatably connected to the driving member 41 and movably connected to the base 10, a second pulling block 43 rotatably connected to the first pulling block 42, and a pulling member 44 connected to the second pulling block 43, penetrated through the supporting seat 20 and connected to the inclined pin member 31. Specifically, in the present embodiment, the driving member 41 can be a cylinder, which is arranged on the bottom plate 11 and located between the two support plates 13. The number of the first pull block 42 and the second pull block 43 are both two and are symmetrically arranged. One end of each first pull block 42 is rotatably connected to the driving member 41. Each first pull block 42 is movably penetrated through the corresponding reinforcement member 62 and the corresponding support plate 13 and the middle part of each first pull block 42 is movably connected to the corresponding support plate 13. The other end of each first pull block 42 is rotatably connected to the corresponding second pull block 43. The two second pull blocks 43 are both located below the top plate 12 and the other end of each second pull block 43 is connected to one end of the corresponding pull member 44. Each second pull block 43 is correspondingly connected to two pull members 44. The other end of each pull member 44 is penetrated through the top plate 12 and the base plate 22 of the bearing seat 20 to be connected to the corresponding oblique pin member 31, wherein the two pull members 44 are connected to the corresponding oblique pin member 31. In this way, by setting the specific structure of the driving assembly 40 including the driving member 41, the first pulling block 42, the second pulling block 43 and the connecting member 44, the driving member 41 drives one end of the first pulling block 42 to move upward. Since the middle part of the first pulling block 42 is movably connected with the support plate 13, the other end of the first pulling block 42 will move downward. The other end of the first pulling block 42 drives the second pulling block 43 and the corresponding two connecting members 44 to move downward. The connecting member 44 drives the corresponding oblique pin member 31 to move downward, thereby compressing the elastic member 33 and pushing the corresponding two clamping members 32 away from each other to clamp the workpiece 200.

[0083] Furthermore, the driving assembly 40 further includes fasteners 45, the number of which is equal to and one-to-one corresponding to the number of the pull-connecting members 44. In this embodiment, each oblique pin member 31 corresponds to two fasteners 45, and each fastener 45 is inserted through the oblique pin member 31 from the side of the oblique pin member 31 away from the bearing seat 20 and connected to the corresponding pull-connecting member 44. In this way, by providing the above-mentioned fasteners 45, the pull-connecting member 44 is connected to the oblique pin member 31 by connecting with the fasteners 45, and the connection method between the driving assembly 40 and the oblique pin member 31 is simple, easy to install and easy to disassemble.

[0084] Further, the driving assembly 40 further includes a connecting shaft 46, the number of which is equal to and corresponds to the number of the first pull blocks 42, wherein a through bar hole 421 is provided in the middle of each first pull block 42, and each connecting shaft 46 is provided on the corresponding support plate 13 of the base 10 and is movably provided in the bar hole 421 of the corresponding first pull block 42. In this embodiment, the connecting shaft 46 can be fixedly connected to the support plate 13. In this way, by providing the above-mentioned connecting shaft 46 and bar hole 421, the first pull block 42 is movably connected to the support plate 13. It can be understood that in other embodiments, the connecting shaft 46 can also be rotatably connected to the support plate 13.

[0085] See also Figure 6 The abutment assembly 50 includes a power member 51 disposed on the top plate 12 of the base 10 and an abutment member 52 connected to the power member 51. In this embodiment, the power member 51 may be a cylinder. The power member 51 is located at one side of the corresponding bearing seat 20. The power member 51 drives the corresponding abutment member 52 to move toward the corresponding bearing seat 20 and causes the abutment member 52 to abut against the workpiece 200 in the bearing groove 21. In this way, by setting the specific structure of the abutment assembly 50 including the power member 51 and the abutment member 52, the abutment assembly 50 can achieve the effect of abutting against the workpiece 200.

[0086] Furthermore, the abutment assembly 50 further includes a plurality of abutment portions 53 disposed on the side of the abutment member 52 away from the power member 51 and corresponding to the number of the workpieces 200, and a connection block 54 disposed between the top plate 12 and the power member 51. Thus, by providing the above-mentioned abutment portions 53, the abutment assembly 50 can independently abut each workpiece 200; by providing the above-mentioned connection block 54, the power member 51 is connected to the top plate 12 of the base 10, thereby ensuring the stability of the connection between the abutment assembly 50 and the base 10.

[0087] Please refer to Figure 1 and Figure 7The clamping process of the clamping mechanism 100 provided in the embodiment of the present application for clamping multiple workpieces 200 is roughly as follows: the multiple workpieces 200 are placed in the multiple bearing grooves 21 respectively, wherein two workpieces 200 are placed on both sides of each clamping assembly 30 respectively, and the clamping mechanism 100 of the embodiment of the present application can place eight workpieces 200 at a time. After the workpieces 200 are placed in the bearing grooves 21, the power member 51 of the abutment assembly 50 drives the abutment member 52 to move toward the corresponding bearing seat 20, so that the abutment portions 53 on the abutment member 52 respectively abut against the corresponding workpieces 200. When the abutment portions 53 abut against the workpieces 200, the power member 51 of the abutment assembly 50 drives the abutment member 52 to move toward the corresponding bearing seat 20. 00, the driving member 41 of the driving assembly 40 drives one end of the first pull block 42 to move upward, and the other end of the first pull block 42 moves downward, and the other end of the first pull block 42 drives the second pull block 43 and the pull member 44 to move downward, and the pull member 44 drives the inclined pin 31 to move downward, and the inclined pin 31 moves downward and compresses the elastic member 33, and at the same time, the inclined pin 31 cooperates with the inclined surface of the corresponding clamping member 32 to push the corresponding two clamping members 32 away from each other, and the two clamping members 32 move away from each other to cooperate with the corresponding stopper 23 respectively to clamp the workpiece 200, thereby clamping the workpiece 200. The external motion mechanism drives the connecting assembly 60 to move, so that the entire clamping mechanism 100 moves, so that the workpiece 200 clamped in the clamping mechanism 100 moves, and the angle of the workpiece 200 is changed, so as to facilitate multi-angle processing of multiple workpieces 200 clamped by the clamping mechanism 100. After the workpiece 200 is processed, the driving member 41 of the driving assembly 40 removes the driving force on the first pulling block 42, and the elastic force of the elastic member 33 in the clamping assembly 30 is released to push the inclined pin member 31 upward. The inclined pin member 31 cooperates with the inclined surface of the corresponding clamping member 32 to push the corresponding two clamping members 32 closer to each other and drive the pulling member 44 to move upward. The pulling member 44 drives the second pulling block 43 and the other end of the first pulling block 42 to move upward, and one end of the first pulling block 42 moves downward and resets the driving member 41. When the inclined pin member 31 is reset, the power member 51 of the abutment assembly 50 drives the abutment member 52 to move away from the supporting seat 20, so that the abutment portion 53 on the abutment member 52 releases the workpiece 200, thereby facilitating the removal of the processed workpiece 200.

[0088] The clamping mechanism 100 provided in the embodiment of the present application, through the cooperation of the supporting seat 20, the clamping assembly 30 and the driving assembly 40, enables the clamping mechanism 100 to achieve the effect of clamping multiple workpieces 200 at a time, which is beneficial to improving the processing efficiency; in addition, since the clamping mechanism 100 can clamp multiple workpieces 200 at a time, and only needs to drive the inclined pin 31 to move through the driving assembly 40 to achieve the effect of clamping multiple workpieces 200 at a time, it saves manpower and reduces the labor intensity of manual labor.

[0089] The clamping mechanism 100 provided in the embodiment of the present application further achieves further fixation of the workpiece 200 through the cooperation of the abutment assembly 50 , and the abutment assembly 50 cooperates with the clamping assembly 30 to ensure the fixing accuracy of the workpiece 200 .

[0090] The clamping mechanism 100 provided in the embodiment of the present application further enables the external motion mechanism to drive the entire clamping mechanism 100 to move through the cooperation of the connecting assembly 60, so that the workpiece 200 clamped by the clamping mechanism 100 can be processed at multiple angles.
